Darwin's Theory
Vocab word for change over time
Evolution
Process by which individuals that are better adapted to their environment are more likely to survive and reproduce more than other members of the same species
Natural Selection
Involves small changes that add up to major changes over a long period of time
Gradualism
What is the name of the islands that Darwin ventured to
Galapagos Islands
More individuals are produced than can survive
Overproduction
True or False If 2 species have similar DNA sequences they’re more closely related
True
A group of similar organisms that can mate with each other and produce offspring
Species
Any difference between members of the same species
Variation
Preserved remains or traces of an organism that lived in the past
Fossils
A trait that increases an organism's ability to survive
Adaptation
Similar structures that related species have inherited from a common ancestor
Homologous Structures
Name 2 pieces of evidence that supports evolution
Fossils, patterns of early development, similar body structures, and similarities in DNA and protein structures all provide evidence that organisms have changed over time
A well tested concept that explains a wide range of observations
Scientific Theory
process of choosing specific organisms to mate in order to create a desired trait
Artificial Selection
Pattern in which species evolve during short periods of rapid change and then don't change much
Punctuated Equilibrium
